BPA markets wholesale electrical power from 31 federal hydroelectric projects in the Northwest, one nonfederal nuclear plant and several small nonfederal power plants.
This section of the site is dedicated to providing information around BPA's current, future and past power and transmission rate cases and tariff proceedings.
BPA works closely with numerous federal and state agencies, tribes, landowners and the public to protect and recover endangered species; protect and preserve our cultural resources; and reduce impacts to wetlands, air, water and the human environment.
BPA supports over 15,000 miles of transmission lines as well as additional fish and wildlife habitat across Washington, Oregon, Montana, Idaho, Wyoming and California. This section provides commonly requested information.
BPA is dedicated to public involvement and transparency. To that end, we hold a number of events and public comment periods to update and receive input from interested parties.
BPA is self-financing, meaning it does not depend on annual appropriations from Congress to fund its operations. Rather, BPA’s operations are funded by revenues from power and transmission customers.
BPA provides about one-third of the electric power generated in the Northwest, primarily from reliable, dispatchable and flexible hydroelectric resources.
When you work at BPA you will be defining the future of energy by finding the lowest cost, most reliable power solutions for Northwest communities and residents.

The purpose of the Grid Access Transformation (GAT) project is to develop changes to BPA processes for evaluation and expansion of the Federal Columbia River Transmission System. It has six main topics: 1) Network Integration Transmission Service Forecasts, 2) Evaluation Criteria, 3) Long-Term Firm Queue Management, 4) Interim Service, 5) Proactive Planning and, 6) Accelerate Expansion. BPA will address NITS Forecasts, Evaluation Criteria, LTF Queue Management and Interim Service in the TC-27 tariff proceeding process, which began in October with pre-proceeding workshops. Proactive Planning and Accelerate Expansion discussions are outside the scope of the TC-27 tariff proceeding and will move forward in a separate and distinct “Future State” engagement series starting in December 2025.
More information on the TC-27 tariff proceeding and the pre-proceeding workshops is available on the TC-27 Tariff Proceeding webpage. Information on the Future State workshops will be posted on this webpage in the sections below.
Background: Some of BPA transmission processes were put on pause while staff evaluate potential solutions it will present to customers and the region in future public meetings. The goal is to make improvements to ensure the Federal Columbia River Transmission System (FCRTS) can reliably meet current and future needs.
This web page is intended to provide workshop materials and other resources to support the collaborative discussions. Any comments, clarifications or questions can be submitted to techforum@bpa.gov with the subject line Grid Access Transformation.
